> Neither is a coroutine in Java using the Coroutines library (Javaflow used thread-locals, but Coroutines doesn't), or a Lua-based coroutine...I'm not sure what you're driving at here?
I'm not familiar with Coroutines or Lua-based coroutines; coroutines are almost always bound to the thread on which they're created, I was pointing out that this is a primary difference between goroutines and coroutines--goroutines are M:N threads.
> BlockingQueues in Java give you that; Go channels don't.
Go channels aren't meant for this purpose; they're synchronization primitives, not dynamic data structures. You can easily build a BlockingQueue in Go.

Can you provide a cite for this? I'm not saying you're wrong, just that I've never heard this assertion before (and I have been doing really stupid stuff with coroutines for way too long). My understanding of a coroutine is just that it's just a cooperatively yielding function where a yield returns a continuation for later resumption.
I don't have a cite for this; almost no coroutine implementations are multiplexed across threads. I spent quite a while Googling around, and I wasn't able to come across any thing. The stuff that I did come across (without searching for 'goroutine') were comparisons of coroutines and goroutines in which one of the defining characteristics seem to be the ability (or inability, in the case of coroutines) to be multiplexed across OS threads.
In general, the term "coroutine" has come to be pretty watered down.
